To all whom 'it may concern IsAK MOELLER, sub]ects ofthe King of Norand residents of New Glasgow, in the ver i Scotia and Dominion of Province of Nova provenient in 'Roller Side Bearings, of which the following is a specilication.

This invention relates to roller side bearings for railway cars. A

The object of the invention is to provide a roller side bearingwhich is simple an for any inequalities, in'- accuracies or .variations in the taperbf the' bolster, in which the roller is self adpistmg to the tilting movement of the car and truck 5 may be one, two, or more as ing by gravity, and

bolste'rs relative to eachl other, in which the -V progect into pockets 15 in the upper portion roller returns to central position in' the hoiis- .which produces a elishioning effect to avoid `load results of shock and jar when the bolsters come together. A The invention comprises the constructionand arrangement of parts hereinafter' described and claimed. l

' In the drawings, which represent one embodiment of the invention, Figure 1 is a plan view; Fig. 2 is a cross section on the line 2-2 Fig. -1; and Fig. 3 -is a view partly in side elevation and partly in longitudinal section on the line 3-3, Fig.' 1.

The side bearing shown comprises a .housing 1 designed for attachment tothe upper or body bolster, but which may be an integral part thereof if desired. Said housing is shown as formed of pressed sheet metal with its upper surface on an incline to suit'the taper of the body bolster indicated at 2. Its upperl portion is provided with the necessary apertures for bolts or'rivets' 3 for securing it to the body bolster, and the central portion of the housing is pressed downwardly to form a hollow housing having side walls 4, pressed to form pockets for strengthening the housing, end walls 5, and a flat bottom, the'bot'tom being punched or sheared out to form an opening 1a through whichthe antifriction member hereinafter described projects .and which` opening leaves inturned flanges or ledges 7 on the'side walls which slope downwardly toward the' center from -each .end of the housing.A

' being shown, is' a roller 8, having two cylindrical yend'portions 9 and a concave central portion 10, the roller at its ends being provided with small trunnions 11 which travel on the ledges 7 of the housing.

cylindrical ,end portions of the antifriction roller roll either directly on the lower bolster itself or on a ilat lever bearing memberli-Xed thereto and indicated at 12. The upper bearing surface consists of a rolledor` pressed metal plate member 13,

d which' is` bent longitudinally between' its side edges into channelor trough form, to a conyex lower surface,14,vvhicli is anti-friction roller. Y Said bearing plate is wider than the distance between .the side.

bearing plate on either side of the channel1 f shape central portion are inclined'with'respect to each other downwardly and invvvardly toward the channel shaped central that avery material clearance iS portion, so

the middle portion of said left between plate andthe upper bolster member, as indicated at 16. `Normally, or when the car is traveling on a straight track the antifriction roller 1s supported by its trunnions 11,

which-rest on the ledges 7 and is out of contact with thelower bolster member. Under these conditions the roller travels 'on its trunnions to central position in the housing so that itv is self-adjusting.

The end walls 5 of the housing form-posiv tive stops which `limit travel of the roller 1n each direction in the housing. car body comes down on the truck bolster as in rounding as curve), the anti-friction member is lifted offv from the ledges 7 and contacts `with the upper bearing member 13. The concavity 10 of the roller and the convex roller surface of the upper bearing Amember compensate for the relative tilting movement between these two membersl as they move vertically with respect to each other, and also Afor variations in the taper of holsters to which the bearing may be applied. The roller rolls along the upper bearing member toward either end of the housing' and when the holsters separate returns to central position as before described.

Since the upper member contacts with the l/Vhen the ear bolster onljv7 at its side edges, it forms in effect a cushion or spring and Yields slightly when contacted by the roller and thereby yavoids' bad effects of shock and jar when the boisters come together. y

vThe bearing described is very simple and 'can' be readily pressed from sheet or plate steel or other metal. It comprises but few parts and is consequently notliable to get out of order and is very durable in service.

What we claim vis:

l. A roller side bearing, comprising 'a housing for ythe Lipper bolster, said housing` being provided with an upper bearing mem-- ber bent longitudinally between its edges into channel form and adapted to yield upwardly and expand laterally when the bolstei's come together, and an anti-friction member having a concavevsurfaceand arranged to roll onf the Channel portion of the upper bearing,l member.

A roller side bearing, comprising a housingfor the upper bolster, said housing being provided with side poeketsan upper f bearing member whose edges project into said pockets, said member being bent'longitudinally between its edges into channel form, and an anti-friotion member arranged to travel longitudinally in said housing and having* a concave surface arranged toy roll on the channel portion of said bearing member.

Aanti-friction travelingr on said supports and arranged to4 vided vvith supports, an upper bearing member inv said housing arranged at each side to contact the upper bolster and bent between its ewigesl into` channel form, and an member having trunnions cooperate with said upper bearing member,

f saidlupper bearing member being arranged to yield when the rbolsters eometogether.

e. A roller side bearing, comprising a housing for the upper bolster, said lfiousing';v

having side Walls provided with. upper pockets and lower supports, an upper bearing member in said housing whose side edges extendintosaid pockets, saidy bearing member beings;` bent longitudinally 'into having trunnons traveling on said supports and having a concave portion tram-'el` ing` on said bearing member, said bearing member being arranged to yield when 'the holsters come together.` y l ln testimony whereof, we have hereunto lchannel form, and an .antrfrietion member
